Upgrades and migration

Commit the application before upgrading. Download the desired signed GitHub Release, replace the complete vendor/rayact_pkgs package set, and update every Rayact file: dependency and override to the matching tarball filename. Keep the entire package set on one version, then run:

npm install
npx rayact migrate
npx rayact prebuild --force

rayact migrate rewrites legacy package imports, converts legacy { name, lib, jsPackage } native-module entries, updates npm dependencies, and regenerates existing native projects. Review the diff before building.

When a module ABI or engine range does not match, prebuild stops with the host and package ranges and asks you to upgrade them together. Do not copy binaries manually to bypass that check. The rayact/mmkv and rayact/secure-store shims are deprecated for 0.0.x; canonical imports are @rayact/mmkv and @rayact/secure-store.
